    • A dust collecting apparatus and method for dedusting a Ca-containing gas using a ceramics filter is provided, in which a filter differential pressure elevation rate is suppressed. A desulferizing agent 103 and a mineral 106 containing MgO are supplied via a hopper 13, 15 a valve 14 and a feeder 16 into a pressurized fluidized-bed combustion furnace 1 together with coal 101 and air 102. A combustion gas 201 is dedusted by a cyclone 2 to become a combustion gas 301, the combustion gas 301 enters a filter container 3a, 3b having a ceramics filter 31a, 31b and is further dedusted. A combustion gas 401 which is dedusted is supplied into a gas turbine 4 to generate power, and combustion gas 501 heats a waste heat recovery boiler 5 which in turn drives a steam turbine 7. The mineral 106 containing MgO is added in the combustion gas 301 which flows in the ceramics filter 31a, 31b. Thereby MgO is added to the combustion gas so that the filter differential pressure elevation rate can be suppressed. The more MgO that is supplied, the greater the effect becomes, and an operation stop due to the differential pressure elevation is eliminated.

    • A trip device of a main circuit breaker is provided which causes only a branch circuit breaker to be set into a tripped state when an abnormal current occurs at a load of the branch circuit breaker while keeping a closed state of the main circuit breaker. The trip device of the circuit breaker has a structure including a trip latch mechanism for opening switching contacts, a stationary core, a movable core which is attracted to the stationary core to release the latch mechanism of a trip lever, an operating pin for interrupting movement of the movable core while the movable core is attracted, an operating spring charged with force when the movable core is attracted, and an inertia roller holding the operating pin, kicked when the operating spring discharges the force, and moved to a position which does not interrupt movement of the movable core. Accordingly, this structure allows a selective tripping system to be implemented simply with small size and low cost.

    • Provided herein is a process for producing methanol which was developed to reduce the emission of carbon dioxide which is responsible for global warming. The process involves the steps of generating steam by the use of nuclear heat of a high-temperature gas-cooled nuclear reactor, decomposing the steam into hydrogen by means of a steam electrolyzer, and synthesizing methanol from this hydrogen and carbon dioxide obtained from a carbon dioxide source. The process also involves the steps of converting carbon dioxide and hydrogen into carbon monoxide and steam by means of a reverse shift reactor, forming hydrogen and carbon monoxide of almost the same composition as the conventional one, and reacting said hydrogen and carbon monoxide into methanol by means of a methanol synthesis column. The process permits the use of an existing methanol production facility. The process may be modified such that the gasified gas composed of carbon monoxide, carbon dioxide, and hydrogen is mixed with hydrogen gas generated by the steam electrolyzer, and the resulting mixed gas is converted into methanol. Also, a power generating plant is provided in which oxygen enriched air, generated by the steam electrolyzer using nuclear heat of the high-temperature gas-cooled nuclear reactor, is used as combustion air.
